 Posted: Sun Apr 23, 2006 4:34 am Post subject: Conditional fields in FORMfields |
 |
|
I need to make a field required only if there is data entered in another (previous) field.
For example:
I create a field for hourly wages, and make it required. But I also need a field for monthly salary and need it to be required, but only if there is no value intered in the hourly wages.
Can, and if so how can this be accomplished
Thanks
Bob |

In this example, we will assume that you require either Hourly Wage or Monthly Salary to be completed, but not both.
Let's say we have the following fields:
| Code: |
$formBean->addField(new DollarField("hourly_wages", "Hourly Wages", NOT_REQUIRED, 5, 1, 5, 1000, 1));
$formBean->addField(new DollarField("monthly_salary", "Monthly Salary", NOT_REQUIRED, 100, 1, 5, 1000, 1));
|
then we can enforce this restriction by adding the following:
| Code: |
...
if (FormField::getOrNull("_submit", $_REQUEST) || FormField::getOrNull("_confirm", $_REQUEST)) {
if ($formBean->isBlank("hourly_wages") && $formBean->isBlank("monthly_salary")) {
$formBean->setError("hourly_wages", "Hourly Wages and Monthly Salary cannot both be blank!");
$formBean->setError("monthly_salary", "Hourly Wages and Monthly Salary cannot both be blank!");
} else if (!$formBean->isBlank("hourly_wages") && !$formBean->isBlank("monthly_salary")) {
$formBean->setError("hourly_wages", "Hourly Wages and Monthly Salary cannot both be filled!");
$formBean->setError("monthly_salary", "Hourly Wages and Monthly Salary cannot both be filled!");
}
if ($formBean->checkValues()) {
if (FF_DISPLAY_CONFIRMATION && !FormField::getOrNull("_confirm", $_REQUEST)) {
// CONFIRMATION OPERATION:

Here is an example of how to make fields appear dynamically when a checkbox is checked.
1. Use FORMgen to generate the form with all the fields, ignoring the conditions:
| Code: |
...
$formBean = new FormBean();
$formBean->addField(new SubmitField("_submit", "Submit"));
$formBean->addField(new SubmitField("clear", "Clear"));
$formBean->addField(new SubmitField("cancel", "Cancel"));
$formBean->addField(new CheckboxField("sports_in_collge", "I played sports in college"));
$formBean->addField(new TextField("sport", "Sport", REQUIRED, 30, 1, null));
$formBean->addField(new TextField("position", "Position", REQUIRED, 30, 1, null));
$formBean->addField(new TextField("college", "College", REQUIRED, 30, 1, null));
...
|
2. Add code to refresh the page when the user clicks the checkbox. Comment out the fields that only display when the check box is checked:
| Code: |
...
$formBean = new FormBean();
$formBean->addField(new SubmitField("_submit", "Submit"));
$formBean->addField(new SubmitField("clear", "Clear"));
$formBean->addField(new SubmitField("cancel", "Cancel"));
$formBean->addField(new CheckboxField("sports_in_collge", "I played sports in college"));
$formBean->formFields["sports_in_collge"]->setExtraHtml("onclick=\"document.forms[0].submit();\"");
//$formBean->addField(new TextField("sport", "Sport", REQUIRED, 30, 1, null));
//$formBean->addField(new TextField("position", "Position", REQUIRED, 30, 1, null));
$formBean->addField(new TextField("college", "College", REQUIRED, 30, 1, null));
...
|
3. Add the code to only display the fields when "I played sports in college" is checked:
| Code: |
...
$formBean = new FormBean();
$formBean->addField(new SubmitField("_submit", "Submit"));
$formBean->addField(new SubmitField("clear", "Clear"));
$formBean->addField(new SubmitField("cancel", "Cancel"));
$formBean->addField(new CheckboxField("sports_in_collge", "I played sports in college"));
$formBean->formFields["sports_in_collge"]->setExtraHtml("onclick=\"document.forms[0].submit();\"");
//$formBean->addField(new TextField("sport", "Sport", REQUIRED, 30, 1, null));
//$formBean->addField(new TextField("position", "Position", REQUIRED, 30, 1, null));
if (FormField::getOrNull("sports_in_collge", $_REQUEST)) {
$formBean->addField(new TextField("sport", "Sport", REQUIRED, 30, 1, null));
$formBean->addField(new TextField("position", "Position", REQUIRED, 30, 1, null));
}
$formBean->addField(new TextField("college", "College", REQUIRED, 30, 1, null));
...
|
4. Add code to remove the conditional fields when clear is clicked:
| Code: |
...
} else if (FormField::getOrNull("clear", $_REQUEST)) {
// CLEAR OPERATION:
$formBean->clearAllData();
unset($formBean->formFields["sport"]);
unset($formBean->formFields["position"]);
} else if (FormField::getOrNull("cancel", $_REQUEST)) {
...

It's possible to use like in the previous example, instead of a checkbox a field DropDownField?, in order that depending on the selected option, a following field appear dynamically.
Thanks in advance.
